否定形式是什么意思否定句怎么改
学点点周老师 2016-06-05 16:23:07
否定形式就是把肯定句改成否定句句中有以下词的,直接在这些词后面加NOT: 1.BE动词(am/is/are/was/were)2.情态动词(can/may/must/need/should.)3.的在其后加NOT,构成时态和语态的助动词(has/have/will/be...) 如: I can swim.-------I can't swim. She will come to see me next week.-----She (will not)(或won't) come to see me next week. 如果没有以上的词,则句子为一般现在时或一般过去时的肯定形式,变否定句时,先将动词变为原形,在动词前面助动词DO(DOES/DID),并在助动词之后加否定词NOT.助动词要根据时态和人称选用相应的.一般现在时用DO/DOES,其中DOES用于第三人称单数主语,DO用于除第三人称单数之外的其它主语.DID用于一般过去时,不论人称. 例如: He goes to school on weekdays.-----He (doesn't go) to school on weekdays. We went shopping last Monday.-------We (didn't go) shopping last Monday. We like watching TV.------We (don't like) watching TV. 另外,除了NOT ,还有一些具有否定意义的词,以上是基本的,先记住这些.以上这些词变疑问也是要提前的.
